Apple rilascia Mountain Lion DP3

Apple ha rilasciato la terza developer preview di OSX 10.8 Mountain Lion: questa versione caratterizzata da numero di build 12A178q è disponibile per gli sviluppatori iscritti regolarmente al programma Mac Developer.

Questa versione corregge moltissimi bug e sistema molte lacune trapelate durante l’uso della seconda beta; nonostante questo rimangono molte problematiche aperte e vi elenchiamo per chi mastica un po’ di inglese le note dei bug ancora presenti:

“Known Issues
- On systems with FileVault enabled, canceling the restart to the Mountain Lion Developer Preview 3 Installer may leave your system unable to present a password dialog at boot time. You
can repair the problem by holding down command-R to boot to the Recovery OS and then using Disk Utility to unlock and Repair your volume.
- Installing OS X 10.8 over 10.7.2 or earlier with FileVault turned on may fail
